What's New - December 2011

December 4, 2011: The original Drag Strip
"Christmas Tree" program simulates the sequenced lights used to control drag
race starts. I recently enhanced the program to drive real lights on a
real model tree using a USB relay board for a drag car owner and
enthusiast. . See
Dragster Tree Relay
Version 2 for more details

A satellite with initial altitude of 1000 miles and 15000 mph velocity will circle the earth in 100 minutes at altitudes from 1000 down to 100 miles above surface |
December 18, 2011: Whew! It has been a busy month between deer hunting, Christmas preparations, and educating myself about how satellites manage to orbit the earth. A decent little 4 point buck is in the freezer, the Mission style bookcase for the wife's scrapbooks finished, and Earth-Sat Satellite Simulator Version 1 was posted today.
Of the three activities, the
simulator took the most time by far, but I now have a pretty good handle on how
and why satellites manage to stay in the sky. I'll be checking and
cleaning up the documentation in the next day or two, but I believe the
program is in pretty good shape.
